Philip Lubin and Partner Propose System to Vaporize Asteroids That Threaten Earth

February 14, 2013

On the eve of a recent Earth fly-by courtesy of the asteroid known as 2012 DA14, physics professor Philip M. Lubin and a Cal Poly researcher unveiled their proposal for a system that could eliminate a threat of this size — half as large as a football field, with energy equal to a large hydrogen bomb — in an hour. The same system could destroy asteroids 10 times larger than 2012 DA14 in about a year, with evaporation starting at a distance as far away as the Sun. READ MORE (UCSB Featured News)
